Several publications are reporting that Windows efficiency tool Ccleaner has been compromised and the compromised version was distributed for over a month to over 2.3 million computers. Our company has never deployed or used this tool, nor advocated it's use. It was originally designed as a way to free up space on hard drives and evolved into a psuedo-privacy tool. I personally used it once in college and it removed some things that I needed, so it left a bit of a distate in my mouth, and I haven't given it a second look.

Anyway, if you use Ccleaner, make sure you are now using the current version, released on or after September 12th - and then once you are up to date with the latest version, I recommend unisntalling it - you don't really need it.
